After more than seven years, DCAA rolled out a fresh looking website. Our quick perusal of the website didn't find too much that is new. Its basically repackaged information that was there previously. We did find a couple of new items (at least new to us).
There a FAQ (Frequently Asked Questions) for contractors that covers many of the misconceptions that contractors and prospective contractors have about DCAA's services (don't call us, we'll call you). It would have been nice for this to have been integrated into the website rather than a .pdf document.
There also a new report on DCAA activities called 2012 Year In Review, which, if a contractor published something similar, would probably be considered unallowable advertising.
Other that those two items, we didn't see anything that wasn't there before. You can still find the DCAA audit programs, its Contract Audit Manual (CAM), recent audit guidance, and a host of checklists and links to other sites for FAR, DoD FAR Supplement, Cost Accounting Standards, etc.
Oh yes, and if you want to go work for DCAA, they've included at least three links on the home page to their "Career Center".
